Abstract :
Several properties of a topological space related to the behavior of open coverings or to the behavior of sequences of continuous real-valued functions defined on the space were recently studied. We modify some notions replacing continuous functions by lower or upper semicontinuous ones and we show that some of so obtained notions coincide with other (continuous case) notions.
